Selected first transition metals like Manganese (II) Iron (III) Cobalt (II), Nickel (II) and Copper (II) complexation with substituted Dehydroacetic acid Chalcone have been prepared and characterized by spectral and analytical technique’s. H1 NMR scans propose decent contribution of trans hydrogen in CH=CH α β unsaturated moiety this is sign of chalcone formation. Electronic absorption spectral data’s of metal coordination compounds moved towards lower or higher wavelength, which confirm the coordination of the Chelato to metal ion which shows the charge transfer band. The prepared Chalcone act as a bidentate ligand for the complexation reaction with Cu(II), Ni(II), Co(II), Mn(II) and Fe(III) ions. Powder X-ray diffractograms studies of the coordination compounds shown that [Fe(C17H16O7)2(H2O)2] and [Mn(C17H16O7)2(H2O)2] are Hexagonal crystal arrangement, whereas Monoclinic crystal arrangement for [Co(C17H16O7)2(H2O)2], [Ni(C17H16O7)2(H2O)2] and [Cu(C17H16O7)2(H2O)2] with P/2 type lattice.
